For most of aviation history, a door on your seat meant first class. Full stop. Business class was fine — lie-flat beds, decent wines, noise-canceling headphones — but privacy was never part of the deal.
That's changed, and fast.
Airlines are now rolling out fully enclosed business class suites on transatlantic routes at a pace that would have seemed absurd a decade ago. The reasons aren't hard to understand: first class cabins are quietly disappearing from most fleets, competition on routes like JFK–LHR has never been fiercer, and passengers who spend $5,000 on a seat have stopped apologizing for wanting a door. Meanwhile, the Airbus A350 and Boeing 787 made smarter, more private cabin configurations physically possible in ways older widebodies couldn't accommodate.
The result is that the transatlantic corridor — New York, Boston, Miami, Los Angeles to London, Paris, Amsterdam, Madrid — has become the proving ground for the best business class products in the sky.
Here's who's delivering and what you actually get.
Business class suites operating now on U.S.–Europe routes
British Airways — Club Suite
British Airways took its time, but the Club Suite was worth waiting for. Gone is the staggered herringbone layout that gave window seats a full wall view and aisle seats a full view of the person beside them. The Club Suite runs 1-2-1 throughout, every seat has direct aisle access, and every seat has a sliding door. No exceptions, no awkward middle pairs.
The suite itself measures around 23 inches wide, the bed stretches to 79 inches fully flat, and the 18.5-inch entertainment screen is one of the more generously sized in the category. What BA gets right is consistency — you're not rolling the dice on whether your particular aircraft has been refitted. Club Suite-equipped planes are primarily A350-1000s, 787-10s, and refurbished 777-300ERs, and they operate almost every major transatlantic route: JFK, Newark, BOS, MIA, ORD, IAD, LAX, and DFW to Heathrow.
If you're booking a transatlantic flight and want a guaranteed suite product today, BA is one of the most reliable bets in the market.
Delta Air Lines — Delta One Suite
Delta deserves credit for being the first U.S. carrier to install business class suites with sliding doors, and the Delta One Suite still holds up well against newer entrants. The walls are taller than most competitors, which makes a genuine difference in how enclosed the space feels when you're trying to sleep at 35,000 feet. Lie-flat bed, direct aisle access, the full package.
These suites fly on the A350-900 and A330-900neo out of Atlanta, JFK, DTW, MSP, SEA, and LAX to Amsterdam, Paris CDG, and London Heathrow. Delta's consistent seat-map labeling makes it reasonably easy to confirm you're getting a suite aircraft before you book — use the seat maps at Seatguru or directly on delta.com and look for the "Delta One Suite" designation, not just "Delta One."
JetBlue — Mint Suites and Mint Studios
JetBlue's Mint is the most interesting product in U.S. aviation right now, and I'll stand behind that opinion. The entire business class cabin — every single seat — is an enclosed suite with a sliding door, a lie-flat bed, and a genuinely thoughtful layout. There's no tiered system where the first row gets something premium and everyone else gets a compromise.
The two front-row Mint Studios take things further with extra surface area, a second side table, and enough room to share a meal with a travel companion. The A321XLR version, now flying JFK and BOS to LHR, LGW, CDG, and AMS, is a narrowbody — but the intimacy of a smaller cabin with a fully enclosed suite works in its favor more than against it.
For New York or Boston travelers, Mint on the A321XLR is the sharpest value in transatlantic business class, especially at the fares we can access through our airline contracts. Retail Mint fares frequently sit at $3,800–$5,500 roundtrip; through CEOFLIGHTS consolidator pricing, that number often drops considerably. Call (888) 851-6897 and ask specifically about JetBlue Mint availability before you assume what's on the screen is the floor.
Air France — new business class suite
Air France has quietly built one of the more elegant suite products in the sky on its refreshed long-haul aircraft. Sliding door, fully flat bed, direct aisle access, and a large HD screen — all of it wrapped in the kind of interior design sensibility that French carriers seem to manage without trying too hard.
The new suites are rolling out on selected 777-300ERs and A350-900s, currently operating from JFK, IAD, and LAX to Paris Charles de Gaulle. More U.S. gateways are being added as additional aircraft get the new cabin. Worth checking aircraft type carefully when booking — Air France is still operating a mixed fleet with older products on some routes.
Iberia — A350 business class suites
Iberia doesn't get enough attention in this conversation, and that's partly because Madrid isn't the first hub that comes to mind for transatlantic travel. But on its newest A350-900 deliveries, Iberia is running a genuinely competitive suite product: sliding door, lie-flat bed, direct aisle access, consistent across the cabin.
Routes include JFK, MIA, ORD, DFW, and BOS to Madrid Barajas. If your itinerary works through MAD — and with Iberia's connections onward to Latin America and Southern Europe, it often can — this is a product worth actively seeking out rather than treating as a fallback.
Airlines bringing new suites to the route soon
American Airlines — Flagship Suites
American's current business class, Flagship Business, is solid but it has no door. The upcoming Flagship Suite fixes that, and from everything previewed so far, it fixes it properly — sliding doors, a fully enclosed footprint, the works. American has been burning credibility on the premium front for a few years; this product is the reset.
Flagship Suites will debut on 787-9 aircraft, launching first on ORD–LHR and PHL to both LHR and ZRH. If you're an AAdvantage loyalist who's been waiting for American to match what Delta and JetBlue have been doing, the wait is nearly over.
LOT Polish Airlines — new business class suites
LOT is the under-the-radar story of this upgrade cycle. The carrier is refurbishing its 787-8 fleet with new suites featuring sliding doors, lie-flat beds, 4K entertainment screens, Bluetooth audio, and wireless charging. This replaces the current 2-2-2 layout — a configuration that was fine for 2015 and is not fine for 2025.
The rollout runs through 2026 across LOT's main U.S. routes: JFK, EWR, ORD, MIA, and LAX to Warsaw Chopin. If you have Polish connections or are routing through Warsaw to Eastern Europe, this is a product worth watching closely.
Lufthansa — Allegris business class
Lufthansa has been promising a premium cabin overhaul for long enough that some frequent flyers had stopped believing it. Allegris is real, it's in service, and the suite version — with sliding doors, a larger entertainment screen, and more personal storage — finally puts Lufthansa in the same conversation as Air France and BA on transatlantic routes.
The rollout is gradual, with new A350-900 deliveries getting the Allegris cabin first. FRA and MUC to JFK, ORD, and BOS are the initial transatlantic targets. One important caveat: Lufthansa will operate both Allegris-equipped and traditionally configured aircraft simultaneously for the foreseeable future. Always confirm the aircraft type before booking — the difference between an Allegris suite and a standard Lufthansa business seat is not minor.
United Airlines — Polaris Studio
United's existing Polaris product is respectable but doorless. The Polaris Studio changes that, adding sliding doors, a larger screen, and an ottoman configuration that allows proper companion dining — something almost no other U.S. carrier offers at this level.
Polaris Studio launches on new 787-9 deliveries in 2026, initially on transatlantic routes from EWR, IAD, and ORD to LHR, CDG, and FRA. United has a large enough narrowbody and widebody fleet that the expansion, once started, should move quickly.
How to actually book the right seat
The single most common mistake premium travelers make is booking "business class" without confirming they're getting a suite-equipped aircraft. Within every airline listed above, older cabin configurations are still flying. Lufthansa will sell you Allegris and traditional Lufthansa Business on the same route on different days. Air France has both its new suite product and its older cabin in rotation. Always pull up the seat map and confirm.
For transatlantic routing through the Middle East, Qatar Airways QSuite via DOH, Emirates' new business class via DXB, and Etihad via AUH are also worth pricing out — particularly if you're on the West Coast or routing to Eastern Europe, where connections can actually be time-competitive with nonstops.
CEOFLIGHTS is ASTA-accredited (member #900292735) and rated 4.8/5 on Trustpilot for exactly this kind of booking. Our airline contracts mean published business class fares on these routes — often $6,000–$9,000 retail roundtrip — regularly come down to levels that make the comparison obvious. Call (888) 851-6897 or reach out directly. Tell us the route, the dates, and which suite products matter to you. We'll tell you what's actually available and what it actually costs.
